Fig. 4 illustrates a somewhat different means for anchoring the centering plate 19 with re-Y spect to the end of the barrel. In this construction, the plate 19 fits tightly in the end of the barrel with the extreme end of the barrel peened over, as indicated -at 24.

What I claim is:

1. In combination.y in a gas gun, a grip or handle, a barrel secured releasably at its rear end to the grip, said barrel having a reduced diameter at the rear end of its bore :adapted to fit the cartridge used Vin the gun and to center it, and having a larger diameter from `Such reduced diameter outward, and a cup member anchored.l
